Apple has rolled out a brand new feature in its Apple Series 4, which is now live for users in the USA. This is an FDA-approved feature that can record an electrocardiogram and record how a person’s heart is functioning.  It can detect irregularities in heartbeat and significantly point out heart conditions like atrial fibrillation. However, the watch cannot detect a stroke, heart attack, or other heart conditions as it records a basic single-lead ECG. It records ECG in few seconds and shows these results: Sinus Rhythm, Atrial Fibrillation or inconclusive.

You can start by installing the software onto Apple Series 4 and get the watch app on iPhone.  In the app, there are different settings to enable a set of notifications to detect an irregular rhythm. Apple will check your rhythm every two hours but will notify you when it spots any irregularity for five consecutive times. All you have to do is rest your arm and place the index finger of the other on the digital crown for 30 seconds. With electrodes at the back of the watch, you are completing an electric circuit to measure the electric signals across the heart.

The positioning of the ECG cushions far from being a replacement for doctors.  Apple will prompt a new user to declare whether they have already been diagnosed with the condition. If yes, it’s not for them. Apple isn’t positioning this device as a monitoring tool for any serious medical condition that has a high risk of getting stroke and heart attack. It is meant for people who don’t know that they have any potentially dangerous condition. Apple has described this device as an “intelligent guardian” for health. This feature will be limited to the users in the US. To be able to use ECG, ensure that the device is updated to watch OS 5.1.2 and paired with an iPhone 5S or above.
